Carbon monoxide (CO) measurements in summertime in Narsaq, South Greenland during Greenfjord 2023

Abstract and dataset contents: This dataset contains measurements of dry carbon monoxide (CO) mixing ratios in parts per million (ppm), obtained using a MIRA Pico portable mid-infrared laser-based gas analyzer (Pico series, Aeris Technologies, Inc., USA). Measurements were carried out at the Narsaq International Research Station (NIRS) in southern Greenland (60.9158°N, 46.0533°W, 17 m above sea level) during the Greenfjord campaign in June-August 2023. Metadata is provided in the file ‘metadata_CO.doc’. Briefly, this dataset file ‘Lv2_CO.csv’ includes: Datetime mixing ratio of dry CO in ppm Pollution flag to inform data user when short-lived spikes can be found in the data from local anthropogenic pollution Funding acknowledgements: This work was supported by funding from the Swiss National Science Foundation grant no. 200021_212101, the Swiss Polar Institute grant no.
